Abstract
Despite the benign features that constitute the majority of pleomorphic adenomas, there are rare instances where malignant transformations have been noted to occur. The most common of these transformations is carcinoma ex-pleomorphic adenomas. This subset can be further classified by unique histological variations that represent their malignant component. We present an unusual case of a rapidly enlarging parotid mass discovered to be a sarcomatoid carcinoma ex pleomorphic adenoma. This case will address the different categories of malignant mixed tumors, discuss the prevalence and clinical relevance of their histological sub classifications, and highlight different treatment modalities.
